From b0ceb4cc4862f3d751973e230569c97e0119aa19 Mon Sep 17 00:00:00 2001 From: Boyuan Zhang Date: Thu, 21 Jul 2016 19:40:19 -0400 Subject: st/va: add preset values for VAAPI encode Add some hardcoded values hardware needs mainly for rate control purpose. With previously hardcoded values for OMX, the rate control result is not correct. This change fixed the rate control result by setting correct values for Vaapi.
